WIRING SYSTEM.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Original application filed July 28, 1914, Serial No. 853,749. Dividedand this application filed February 2, 1915. Serial No. 5,713.-

To all whom it may concern Be it known that I, EDGAR A. WALZ, J r., acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Wiring Systems, of which the following is aspecification.

My invention relates to new and useful improvements in directionsignaling systems for vehicles, being a division of my copendingapplication, filed July 28, 1914, and bearing the Serial No. 853,749.

The primary object of my invention consists in the provision of anextremely simple and efficient form of direction signaling system of thevisual type, in which the signals are given by the selective lighting ofone or more of a plurality of electric lights.

A further object of my invention is the provision ofa signaling systemarranged to display corresponding signals at both the front and rear ofa vehicle, the lights of the signal being included in circuitscontrolled by switches, preferably in the form of push buttons, mounteddirectly upon the steering wheel of the vehicle or at any other desiredpoint.

A still further object of my invention consists in the provision of anadditional signal, usually audible, to enable the driver of the vehicleto tell whether the direction indicating signals are working properly.

With these and other objectsin view, my invention will be more fullydescribed, illustrated in the accompanying drawings, and thenspecifically pointed out in the claims which are attached to and form apart of this application. 7

The drawings illustrate diagrammatically the preferred embodiment of myinvention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

My signaling system, in its preferred form, includes a pair of forwardlights 10 and 11, a pair of rear lights 12and 13 and a tail light 14,these lights being each mounted in any suitable type of casing.- It alsoincludes an additional signaling device, such as a buzzer 15, the latterbeing preferably mounted upon the dash of the vehicle. A

feed Wire 16 leads from the positive pole of' a battery 17 to a commonfeed wire 18 which runs longitudinally of the vehicle, terminating atits front end in leads 19 and 20 to contacts of the lights 10 and 11 andat its rear end in leads 21, 22 and 23 to contacts of the light socketsof the lights 12, 13 and 14. A wire 24 connects the free contacts of thelight sockets of the lights 11' and 13, forming a part of a commonreturn circuit for such lights, and a wire 25 connects the free contactsof the light sockets of the'lights l0 and 11, forming a part of a commonreturn circuit for said lights. Return wires 26 and 27 lead from thewires 24 and 25, respectively, to a contact of the push button switches28 and 29. A wire 30 leads from the other contact of the switch 28 to awire 31 leading from the other contact of the switch button 29 to oneterminal of a her 36 carriesa contact 38 engageable with a contact 39when the armature 35 is drawn into engagement with the electro-magnet34, this latter contact 39 being included in the wire 33 forming part ofa common return circuit for the lights 10, 11, 12 and 13.

A wire 40 leads from the feed Wire 16 to one terminal of the buzzer 15and a wire 41 leads from the other terminal of the buzzer to the contactmember 36. A wire 42 leads from the free contact of the light socket ofthe light 14 to one contact of a manually operable switch 43 and a wire44 leads from the other contact of this switch to the-coin mon returnwire 33.

The foregoing description, particularly when taken in connection withthe drawings,-

is believed to constitute such a clear disclosure of my invention aswill render any detailed description of its operation unnecessary.Should the driver of the vehicle wish to turn to the right, he willclose the circuit through the push button 29, under .which conditions,current will flow from the battery through the wire 16 and wire 18 tothe loads 19 and 21, so through the lights 10 and 12 to the return wire25, through the wire 27 and push button 29 to the wire 31,

through the electro-magnet 34 and wire 33 back to the battery. On theother hand, if the driver wishes to turn to the left, he will close thecircuit through the push button 28 when a circuit from the batterythrough the wires 16 and 18, leads 20 and 22, lights 11 and 13, wire 24,wire 26, push button 28, wires 30 and 31, electro-magnet 34 and wire 33to thebattery will be formed. If, again, the driver wishes to stop orreverse the car, he will close both the above described circuits bysimultaneously operating both push buttons. It will be noted thatcurrent will at all times pass to the tail light 14 unless its separatecontrolling switch 43 is opened.

As above set forth, the circuits for both the lights at the right andthe lights at the left of the vehicle pass through the electromagnet 34of the relay 32. This relay is so adjusted that such increase in currentin the common return circuit as would be caused by the energizing of twolights at once, such as the lights 10 and 12, would energize the relayto make it attract its armature and so close a circuit through thebuzzer. The driver can, therefore, always tell, upon closing of eithercircuit, whether both lights in the circuit are energizedor not and is,therefore, always certain that his signal is being ven. It will ofcourse be clear that my system may be modified to include only a singlepair of direction indicating lights, the buzzer and the relay, eachlight being in an independently controlled circuit. If this is the case,the relay is, of course, arranged to attract its armature upon passageof such current through the common return circuit as would be necessaryto energize a single light. I therefore reserve the right to make anychanges in the arrangement of lights and wiring which may come withinthe scope of the appended claims, without in the the circuit, a secondcircuit closed by the closing of the relay, and an additional signaldevice in the second circuit, the relay being arranged to close onlyupon passage of current through the common circuit of sufficientstrength to energize all signal devices therein.

2. In direction signaling systems for vehicles, a pair of independentfront signals, a pair of independent rear signals, a circuit common toone signal of each pair, a second circuit common to the other signals,means for selectively closing such circuits, an audible signaling devicein a circuit common to both circuits, and resistance operated meanscontrolling the sounding of such signal, whereby the signal will remainsilent unless all signals in either of the first circuits are energized.

3. In direction signaling systems for vehicles, a pair of independentfront signals, a pair of independent rear signals, a circuit common toone signal of each pair, a second circuit common to the other signals,means for selectively closing such circuits, an additional signalingdevice in a circuit common to both circuits, and resistance operatedmeans controlling the energization of said additional signal, wherebysuch additional signal will not be energized unless all signals in oneor the other of the first circuits are energized.

In testimony whereof I alfix my signature in presence of twowitnesses.
